QMK beamspring controller kit
USBC With solenoid driver and cable
these are QMK driven beam spring controllers for the 3278 5251 3101, basically most models that have a removable controller, just not the display writer or 4978.
this is a full beam spring kit, the cable, the controller, and a solenoid driver all in the one kit, no looking for solenoid drivers anymore!
To go to the QMK configurator I will give you the link you will need to scroll through the menu and then select the universal option for your keyboard and then go build your layout in the configurator and then you will need to compile it and flash it in QMK tool box. pre flashed on is my 5251 layout I use for testing these things.  if you have questions about this thing, ask me, and if I don't know, I know the devs of the controllers and can get answers out of them relatively quickly if need be.
the testing is all done on a 5251 the 3278 may need a bit of a notch cut out of the other side of the connector and if you need that ask me I can do that  by default they ship with a straight connector for the solenoid but if you want a 90degree one I can change it.
These things are known to be tricky to get perfect pin alignment, you must verify all the pins are aligned perfectly, I get many messages asking why it won't work and it is this alot of the time.
If you would like me to send a picture of the tedt reading before sending your controller LMK, you can have me test on a 5251 or 75 key 3278, i have both at the time of posting this
